How do you find an inequality on a graph ?

Answer 1

There are three steps:Rearrange the equation so "y" is on the left and everything else on the right.Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).
